We booked four days but only stayed one. It was that bad. First thing to know, the pictures in the listing are not the unit you will stay in. So do not go by the photos. The best way to describe is that it appears there were very long term residents who lived, who only recently moved out. Nothing has been done to clean, repair, or beautiful the place. The guest bed had oil/sweat stains where it was clear a person had slept at for years. Water damage and stain were all over the walls. Just next to the master bed was a wall covered in mold and water damage. The kitchen has years of grease stains on the blinds and walls that have not been cleaned. Shelves and side tables are broken. The faucet in the main bathroom sprayed everywhere but into the sink. The pool was empty except for half a meter of brown water. By now you should have a pretty good idea of why we ended our stay early. It is indeed big and just next to Bumrungrad hospital. But I could never recommend this to anybody.
